Why anyone want to listen to this self promoting person is beyond me.
People who get paid more are always going to get more back, but lets face it they pay a lot more to begin with. If it's all offset, then why change it? If you want people to be better off then drop the GST on Bread, milk, butter - actually all food! (no doubt they count because it's too hard to define it - how about a common sense definition - or better still a list!) and while they're at it they could start calculating the GST on petrol correctly instead of on top of the road tax.
if you want a greater return then go get a job that pays more. Don't moan that someone on a higher wage will get a greater return than you. They shouldn't have to pay more than their fair share so you can have government supplied services, pay your fair share. As for property tax, people have been claiming depreciation while their price of their house has been rapidly increasing over the years. It is a loophole that needed to be closed, but that Helen who had substantial rental properties wouldn't touch, i wonder why.
